Patented Nov. 26, 1929 DAVID GEDDES, OF BERKELEY, CALIFORNIA ELEVATOR BUCKET Application filed November 1, 1926.

The object of my invention is to produce, from a single sheet metal blank, a satisfactory and efi'icient bucket for ready attachment to endless belts.

The accompanying drawings illustrate my invention.

Fig. 1 is a side elevation of a bucket embodying my invention;

Fig. 2 is a rear elevation of a slightly modified form;

Fig. 3 a vertical section; v

Fig. 4 a plan of the blank used in forming the bucket shown in Fig. 1, and,

Fig. 5 a plan of the blank used in forming the bucket shown in Fig. 2.

Ref rring first to Figs. 1, 3 and 4, the bucket is formed from a blank having a middle rectangular portion 10, flanking triangn la-r portions 11, 11, a lip 12 at the outer edge of each portion 11, an car 13 at the lower end of each lip 12, a prong 14L- at the side of each lip 12, and a tongue 15 at the middle of the lower edge or" the central portion 10.

The blank is bent into bucket shape by folding on the folded lines 16, 16 and 17, 17, ears 13 being bent on the fold lines 18, 18 to engage the front surface of central portion 10 after lips 12 have been bent at right angles to the plane of the triangular portions 11,-

and the tongue'15 being bent inwardly towards the inner surface of the middle portion 10 until it lies in the plane of the folded lips 12.

Prongs 14 are folded on the fold lines 20, 21 and 22 (which are spaced from each other approximately the thickness of the belt 25) and are projected through the belt first in one direction and then in the other, the tips of the prongs finally entering perforations 26.

In the construction shown in Figs. 2 and 5 the blank is the same as the blank shown in Fig. 4 except that, instead of the short tongue 15, I provide. a longer tongue 15 and provide the end of this tongue with a prong 27 similar to prongs 14:.

The width of tongues 15 and 15 is substantially equal to the distance between the adjacent edges of the lips 12 when said lips Serial No. 145,390.

have been folded into bucket-forming position.

I claim as my invention:

1. An elevator bucket if rmed from .a sheet metal blank comprising a middle portion, flanking ioldable triangular portions bendable into planes at a substantial angle to the middle portion, a lip at the outer edge of each triangular portion and bendable into planes converging with the plane or" the middle portion and sharpened prongs carried at the free edges of said lips and projectible through a carrying belt.

2.;An elevator bucket formed from a sheet metal blank comprising a middle portion,' flanking ioldable triangular portions bendable into planes at a substantial angle to the middle portion, alip at the outer edge of each triangular portion and bendable into panes converging with the plane of the middle portion, ears carried by one end of each or the lips and bendable into overlapping relationship upon the middle portion, a tongue at the lower edge of the middle portion and bendable into the final plane of the aforesaid lips and bridging the space therebetween, and sharpened prongs carried at the free edges of said lips and projectible through a carrying belt.

In witness whereof, I have hereunto my hand at Guadalajara, Jalisco, Mexico, this 21st day of October, A. D. one thousand nine hundred and twenty six.

DAVID GEDDES.
